Update
- There have been a couple reports that the No Petty Jobs function can bug out the sowing entirely. While I wasn't able to reproduce this problem, looking over the code closely I did spot one edge case scenario in which the sowing flag could get stuck if a number of conditions were met. This has been fixed.
- Some minor optimizations applied while I was looking over everything closely.

The harvest if threatened now ignores plants not sensitive to the cold, like healroot.

Fixes Harvest Now gizmo not working for zones in caves

Slight adjust to message warnings to avoid spam

New
- Harvest early if threatened: a new mod option which will designate a zone for an immediate harvest if tonight's weather looks to be deadly cold.

This especially pairs well with the smart sow option, which will let sowing happening if a plant are predicted to reach their minimum harvest threshold (usually 65%), because normally pawns will not automatically harvest until 100% growth. With these two features combined, the whole process is much better automated, no micro-management needed.
- Improved the logging
- Minor code optimizations

New
- You can now set the sow mode and priority level of multiple zones at once, even if they don't have the same initial configurations. Doing so will sync them all together to use the same settings.
- As part of these changes, gizmo handling for this mod has been rewritten entirely and is now cached, greatly improving performance while a zone is selected.

Note: at the time of this writing, there is a slight visual glitch with gizmos if you use the mod Performance Optimizer due to the way it caches gizmos. An investigation request has been put in with its author.

Hotfix: Fixes an issue with existing saves trying to install this mod. This had to do with the performance caching in the previous update needing to take place earlier in the code.

New
- Prediction now considers plant rotting. For example plants that can survive the winter but will likely die of old age before maturity, due to slow growth over winter.
- Major performance improvements. An optimized version of rimworld's temperature forecaster has been written up, able to run the internal plant simulation in only 1/10th the time compared to before. Overall, the entire mod is about 70% faster.
- Improved accuracy. Before, if you were settled around +/- 90 degrees latitude, the temperature prediction could be several degrees off due to variance in sunrise/sunset. This is now accurately factored.
- There is now a new mod option called Allow cold sowing. When disabled, smart sow will not allow sowing into freezing soils. This option exists for those who wish to respect vanilla's normal rules.

- Fixed an NRE that could happen when making a new zone in some conditions.
- Some logic optimization regarding how and when cache data is refreshed.

- Slight tweak to the cache improvements in the previous update.
